| Engineering Journal 7.3.1.1: The ipx routing Command To enable IPX routing, use the ipx routing in global configuration mode. The full syntax of the command is ipx routing [node] To disable IPX routing, use the no form of this command: no ipx routing [node] The argument node indicates the node number of the router. This is a 48-bit value represented by a dotted triplet of four-digit hexadecimal numbers (xxxx.xxxx.xxxx). If you omit node, the router uses the hardware MAC address currently assigned to it as its node address. This is the MAC address of the first Ethernet, Token Ring, or FDDI interface card. If no satisfactory interfaces are present in the router (such as only serial interfaces), you must specify node. The ipx routing command enables the IPX RIP and SAP services on the router. If you omit the argument node and if the MAC address later changes, the IPX node address automatically changes to the new address. However, connectivity might be lost between the time that the MAC address changes and the time that the IPX clients and servers learn the router's new address. The following example enables IPX routing: Router(config)# ipx routing
